Yuki Cross

Yuki cross (later on known as Yuki Kuran)has been the adopted daughter of Headmaster Cross, a former vampire hunter, and she is a member of the Disciplinary Committee, also known as a Prefect (Guardian) ever since Rido Kuran, Yuki's uncle, killed her parents, Juri and Haruka Kuran. Yuki however has no memory of this or any part of her life before she was "5", which is when Kaname saved her from a Level E, because Juri Kuran used vampire magic to put Yuki's vampire side (and all her memories along with it) asleep. She, like Chairman Cross, believes that vampires and humans can live together peacefully. She also has been giving her childhood friend Zero her blood to save him from becoming a Level E vampire. She and Kaname were raised as siblings by Yuki's parents, Juri and Haruka Kuran, who were also heads of the Kuran line of pureblood vampires, and with Yuki's parents and her real brother gone, she is the apparent heir of the Kuran vampire throne. She is also Kaname's fiance, whom she remembers as her brother, and Kaname has yet to tell her the truth about his real history. Yuki loves Kaname who has always been protecting her and by her side during all her childhood as a human and as a vampire but is confused by Zero's feelings for her. We are told that Juri and Haruka Kuran were also siblings. When Rido Kuran, Yuki's uncle, resurfaces at Cross Academy, Kaname awakens her vampiric side and pureblood powers.
